SNVS556C – APRIL 2008 – REVISED JANUARY 2016 LM2738 550-kHz/1.6-MHz 1.5-A Step-Down DC-DC Switching Regulator
1 Features 3 Description The LM2738 regulator is a monolithic, highfrequency, PWM step-down DC-DC converter in an 8pin WSON or 8-pin MSOP-PowerPAD package. It
provides all the active functions for local DC-DC
conversion with fast transient response and accurate
regulation in the smallest possible PCB area. 1 Space-Saving WSON and MSOP-PowerPADв„ў
